% For the \newcommand part, e.g. \newcommand{\CC}{\mathbb{C}}, all you need to know is that
% the 'newcommand' is in the first bracket and the effects are in the last bracket. So if you
% want to type \mathbb{C}, you can simply type \CC. For commands defined with a '[]' in the
% middle, it means that you can use certain parameters. e.g. \newcommand{\lleq}[1]{\xlongequal{\mathrm{#1}}}.
% If you want to type '\xlongequal{\mathrm{Lemma}}', you can simply type '\lleq{Lemma}'.

% Problem with the 'lstlisting' environment: please make sure that there are EXACTLY 16 (or usually 4
% TAB sizes) before the leftmost character.
